Abstract:
Among strategies for decreasing diseases, the use of larvicidal plant extracts against mosquito larvae
gain an important place in vector control. The aim of the present study was to reveal the insecticidal
effectiveness of an endemic medicinal plant on Mosquito-Borne Diseases. The chemical composition
of the dried aerial part from Origanum floribundum Essential oil, obtained by hydrodistillation, was
characterized by Fourier-transform infrared (FTIR) spectroscopy and gas chromatography-mass
spectrometer (GC-MS) system. The potential larvicidal activity of this extract as bioinsecticide was
assessed against Culex pipiens. Results showed many functional groups such as phenols and alcohols,
besides, the chemical composition by GC-MS identified thymol (86.9%) and p-Cymene (5.1%) as major
components. A significant larvicidal effect against the target mosquito species was noted, with values of
LC50 at 21.19 mg/l and LC90 at 68.37 mg/l. The results obtained showed that the essential oil of Origanum
floribundum with chemotype thymol possess a potent larvicidal activity and could be considered as an
eco-friendly alternative for vector control.
